As you’re wrapping up your fall yard work, please remember to rake or blow your leaves away from the lake and not into it.
It is inevitable that some leaves will naturally fall into the lake, however, an abundance of decomposing leaves will increase the nutrient levels in the lake which can lead to algae blooms and greater aquatic weed growth near your property. As an overabundance of algae and weeds die, they decay, causing bacteria to use up the oxygen in the water. This can kill fish and other aquatic life.

Leaves are a seasonal pain in the neck but we need to think of our beautiful lake, long term.
Mulch them into the lawn, compost them or take them to the Town of Sand Lake Department of Public Works off Thais Road. Hours: M-F 7 AM – 3 PM

Investigating Harmful Algal Bloom On LG:
The follow-up and initial identification was all done by the LGA’s Kristen Wilde, whose family has lived on the Lake for generations.
The LGA sounded the alarm, and marshaled the resources needed to investigate the bloom quickly.
Here’s what else the LGA is doing for our Lake:
We need your help to prevent future outbreaks. Here’s what you can do now:
We’ve all got to act now if we want to protect the water quality of our Lake.
If you see changes in the water around your property, please take a photo and note the location and send it to: email@example.com.

Common Aquatic Invasive Species of NY
- This Department of Environmental Conservation [DEC] chart contains some of the more common aquatic invasive species found in New York, the areas of the state they currently inhabit, and the control strategy recommended to ensure that they are not spread to new waters via boating and fishing equipment.
- For more detailed information visit A Field Guide of Aquatic Plant Species Found in New York Lakes along with Potential Exotic Invaders.
Brazilian Elodea stems have numerous branches and can grow over 20 ft. in length. Is often confused with hydrilla and native elodea. Lance-shaped leaves are about 1/8 inches wide and 1.5 inches long and often have very minute teeth along the edges that may require magnification to see. Leaves are arranged in whorls around the stem with each whorl composed of 4 to 6 leaves. The number of leaves per whorls doubles or triples every 8 to 12 nodes. These “double nodes” are the only place where branches occur along the stem.
Brittle Naiad leaves are opposite (in pairs along the stem), but sometimes appear to be in a whorl at the tip. Leaves are 1-2 inches long, toothed, stiff and pointed. Plant is very brittle and easily breaks into pieces.
Curly-leaf Pondweed stems are branched and somewhat flattened. Leaves are reddish-brown in color, oblong and about 3 inches long. Leaves are usually stiff and crinkled and unlike other pondweeds have finely toothed edges.
European Frogbit floating leaves are heart-shaped and 1-2 inches wide. They resemble the leaves of a miniature waterlily, veined on top and dark purplish red with a spongy coating on the underside. The plant has numerous roots up to 12 inches in length that float freely under the plant.
Eurasian Watermilfoil stems are usually 3 to 10 feet in length and can range from pale pink to reddish brown in color. Bright green feathery leaves are finely divided and occur in whorls (circles) around the stem. Each leaf has 12-21 leaflet pairs. Native northern watermilfoil which it can commonly be confused with has 5-10 leaflet pairs.
Fanwort stems are long and appear tubular. Leaves are fan-like with a short stem and are arranged opposite each other on the stem. Plants have white to light pink flowers that float on the surface.
Hydrilla plants looks very similar to Brazilian elodea and other native Elodeas. Northern plants often lack the spiny underleaf and finely toothed leaves may be difficult to see. Best distinguishing characteristic is the turion or bulb connected to its roots that the other plants lack.
Variable Leaf Milfoil leaves are similar to Eurasian watermilfoil except each leaf has 5-14 leaflets. As the stem reaches the surface it changes its growth pattern to become a stout emergent flower-spike carrying an entirely different type of leaf. These emergent leaves are stalkless, wedge-shaped, stiff, and pointed, with variably-toothed margins.
Water Chestnut stems are very flexible and can reach 12 to 15 ft. in length. On the waters surface the plant contains a circular cluster of saw-toothed edged, triangular floating leaves that are connected to an inflated petiole (bladder) that provides added floatation. Feather-like leaves can be found along the submerged stem. Fruit is a nut with four 1/2 inch barbed spines.
Parrot Feather woody stems can grow over 5 feet in length, often extending outward onto the bank or shore. Emergent leaves are bright blue-green, rigid and deeply serrated. Leaves are arranged in whorls of 4-6 around the stem, with each leaf containing 10-18 segments. The leaves can extend 12″ out of the water and look like miniature fir trees. The underwater leaves are red-brown in color and have 20-30 segments per leaf. They appear to be decaying and are often confused with Eurasian watermilfoil leaves.
Creeping Water Primrose leaves are willow-like and are alternately arranged on hollow red stems. Young leaves may be rounded. Has bright yellow flowers from spring – fall. Sprawling growth habit that forms dense mats.
Water Quality Committee
We have an active Water Quality Committee in place which is collaborating with the New York State Federation of Lake Associations [NYSFOLA] and the DEC to monitor the quality of the water in Glass Lake. Members of this committee – Dave and Linda Cairns; Barth Neitzel; Jeff Clark and Al Aita have recently completed a full days training in Hamilton, NY on how to collect and handle water specimens taken at different lake depths so they can then be sent on to the DEC for analyses. This information and its interpretation will then be sent to us.
June 17, 2017 was the second day for collecting samples, which are taken every 2 weeks for 10 weeks during the summer months with a 5 year commitment. As such we owe these individuals a round of thanks for the time they have already put into this and to their long term commitment to this program.
Their efforts highlight for us the stewardship responsibility that we all have for our lake, and the need to avoid any possible pollution.
At the Annual Meeting of June 17, 2017, the membership discussed the issue of inadvertent oil and gas spills, and the importance of not putting any foreign objects into the lake.
Diet for a Small Lake – Written in 2009 as part of a collaboration between the DEC Division of Water and the New York State Federation of Lake Associations, the second edition of Diet for a Small Lake is a significantly updated version of the 1990 publication sharing the same name. HTML version
